Pyromorphite -unusual botryoidal form
Manhan (loudville) lead Mine, Southampton, Hampshire County
5.9 x 3.5 x 2.7 CM (cabinet)
A very unusual and oddly attractive old Pyromorphite specimen from the Manhan Lead mine in Massachusetts which is the oldest Lead mine in North America (1679). The matrix is covered on one face with a smooth olive green botryoidal surface of layered Pyro. Ex. John Marshall collection, I have seen this habit a few times before but it is rare at this locality which usually has small bright green to brown crystals. This habit does not even look like a Pyromorphite, but close exam and strong magnification show it is indeed. This specimen is by far the best of this sort I know of, esthetic and in very fine condition.
Royalston Massachusetts is a legendary classic locality for gem Beryl with occasional finds over the past 180 years. This specimen shows the typical habit with a single crystal 5.4 CM long that is nearly all gem clear. The crystal also shows an old break that is rehealed with a thin line of Quartz dividing the prism into two sections. Much prized by collectors of classic minerals, these are not often available. One old repair is noted on close exam but nearly all of these have at least one.
Fluorapatite w Albite and Chlorite
Acushnet Quarry (Warren Bros.) Acushnet, Bristol County

new june 17
Apatite on Adularia from the Acushnet Quarry are not often available, and are prized by Northeastern US collectors and Apatite lovers worldwide. A classic Alpine cleft find these look identical to some European specimens. This has a complete floater Albite crystal coated with Chlorite and hosting a compound Apatite crystal almost 2 CM across. Collected by the legendary Ernie Schlichter probably in the early 1980s. Undamaged and complete, the color is yellow-green grading to white, and little richer in person.
Simeone Quarry, Wrentham

pre Tucson 2015 update
A small but well defined Massachusetts Amethyst in scepters and parallel growths. Sharp with good clarity and subdued zoned color, this is for its size a very fine specimen from this locale. A fair sized contact on the edge back is not seen when mounted for display. All of the three top tips are perfectly undamaged even at 30X magnification. Very few were found in this condition.
A classic old locality! This is quite a nice and rare combo, from the Lane Quarry in Massachusetts. Cut and rough combo with a fine faceted stone of light yellow color and excellent clarity. Datolite is a rare gemstone and it is difficult to cut as the hardness varies in different orientations, but when done well they are brilliant! Datolites can have a dispersion greater than diamond. The crystal is bright, sharp and un-dinged on the display side, contacted on back and broken on the base, it displays well. Very uncommon to see a Massachusetts Datolite combo like this!
Impressive and a Northeastern US classic! Sharp, clear and bright gemmy Datolites up to 2.4 CM with selective faces colored a nice cognac hue sit on a contrasting green Prehnite. As esthetic as you can find, the main crystals are in perfect condition but non detracting damage is noted on a few smaller crystals and at the edges. Despite this it displays very well and is a striking specimen from this old locale.
A Massachusetts rarity, from the John Marshall collection from a one time find over 40 years ago, during the construction of I 495. Two large, complex pyrites to 4.4 CM are perched on a jumble of micro crystals mostly Magnetites with numerous Xenotime. The right side crystal is in perfect condition, the left shows an old stress crack that is partly rehealed. An exceptional example of this find, I have not seen any better ever. Displays well.
